I think you could factorise this logic in a dedicated method.
It would improve the code maintenance and readability.

Maybe there is already a method for this purpose in the existing code.

  describe('with a group_by_date_field  field having a conventional name', () => {
    it('should generate a valid SQL query', (done) => {
